To all whom 'it may concern.'

Be it known that I, HARRY citizen of the United States, residing at Sandwich, in the county of Dekalb and State of Illinois, have invented a certain new and useful Improvement in Substation Signal-Receiving Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this speciiication.

My invention' relates to substation receiving devices used in signaling systems and has forits object the provision of a step-by-step selective signaling device in which certain features of objectionable operation in prior 0. RUGH, a

devices are obviated. In the general form of such devices it has been customary to provide an 4arm preferably angularly ydisplaced from other arms of the other'statons on the line and which arm is designed to make contact with a contact making device and if this contact is continued for a long enough period the said local signaling device operatcs. The arrangement generally has been such that if the arm makes but a momentary or passing contact with the contact making device that the signaling device Vdoes not respond. To prevent this response of the local signaling device during the momentary contact when the arm is passing the contact making device when a station having a greater number of impulses is being called, it is necessary to make the adjustment of the local signaling device, which is usually a vibrating bell, very strong. By this, I mean that the spring or other retaining device which is associated with the armature must have a great amount of tension so that the bell will not respond except when the current is continued for al longtime. This, it will be seen, makes the loperation of the bell marginal i'n that a weakcurrent may not operate the said bell as against the strong spring adjustment even though the current were long continued. It is :of 'Great advaiiitage therefore that this margina adjustment of the bell or local substivtion'signal controlling device be eliminated; To eliminate this objectionable feature is the'object .of my invention. The means which I use to accomplish this obje'cnof course, are susceptible of Specification oi Letters Patent. I

. more'particularly by Patented aug. 311, 1914i., This application filed September application to4 most, systems, but I illustrate my invention herein as applied to a given particular system, which system also has some novel features. The application of my system for eliminating the mar inal feature of the substation signal will is readily apparent to those skilled in the art.

In the explanation of the invention therefore lin connection with the accompanying drawing, I wish it understood that this illus tration is taken merely as an indication of one of the many forms in which the invention may be utilized.

I will describe one form of my invention reference to the accompanving drawing in which:

Figure 1 diagrammatically sets forth a system constructed in accordance with my invention, and: Fig. 2 is a simplitied diagrammatic view more clearly to reveal the circuit arrangements thereof.

In Fig. 1, I illustrate a central station A and substations B and C all united by line conductors 1 and 2. At the central station I show a battery 3, a push button 4f, and a con! tact therefor 5. The elements 4 and 5 are merely illustrative off any suitable calling mechanism for sending impulses, if as iii the specific illustration herein the substation devices are selected depending upon the number of impulses transmitted. At the substations I illustrate a step-by-step clement 6 carrying an arm 7 adapted when in proper .position to contact with a spring 8. A stop 9 is provided for the step-by-step element, and a spring 10 to restore it to normal against the stop 9, when certain operating pawls to be described later vare released from engagement with said element G. The arms 7 at the various substations occupyl different angular positions so that ditlerent stations vrespond operatively by their signals to diierent'nurnber's of impulses. A step-up pawl 11 actuated by an arinature12 steps up `the ele-i ment 6 in response to i'inpulses. ture 12 is under the controljoit a relay'l. A second pawl which might *call'the holding pawl 14 is under the control of an armature 15, which armature is inductively associatedwith the relayvl. .A back stop `17 is provided for the armature 12 and a front if not all, step-by-step4 The armastop 18 is provided-for the armature A back contact 19 is provided. forthe armature .15 andy a .front contact20 is provided for the amature 12. A buttonA 21 is preferably placedbe'tween the pawls.14 and 11 so that the pawl 11 is .removed from element 6 by the awl 14, and at the same time there will not too much friction between these two pawls. A local signal 22is provided which 1s so designed herein that it will operate by virtue' of current? furnished from the central station. a

In 'associating the devic'es in circuit I have a'conductor 23 which unites one terminal ofthe magnet 13 with the conductor 2.

,A conductor 24 unites the other terminal of the magnet 13 with the magnet 16 and a conductor 25 unites'the other terminal of' the magnet 16 with the line wire 1. The 4-front contact: 20 of the magnet 13 is by means of a conductor 26 connected to the conductor 24. A conductor 27 connects the conductor 25 with the spring 8. A conv ductor 28 connects one terminal of the bell 22with the line wire 2. A conductor 29 connests' the other terminal of the bell 22 with the back contact 19. A conductor 30 connects the arm 7 with the amature 15 and a conductor 31 connects the armature 15 with the armature 12. lThese circuit arrangements will be clear from an inspection of Fig.- 2. It will. then be seen that magnets 13l and 16 are 'arranged in series in av bridge across the line conductors'l and 2. It will also be Aseen that the local be1l'22 is arranged for bridge connection across the conductors `1'and 2 lthrough circuit includ- -ing .conductor 28, bell 22, conductor 29, contact 19,.armature 15, conductor 30, arm 7, 'spring 82 conductor 27, conductor 25 to line It will alsobe seen that when the armature'12 is pulled up to engage the contact- 20, the 'magnet 16 is short circuited by reason' of the circuit that extends 4from line wire 2, conductor 23, magnet 13, conductor 24,

conductor 26, contact 20, armature 12, con-` ductor 31', conductor 30arm 7, spring 8, 'conductor 27,to line-w1re 1. This means that there is practically a short circuit from the conductor 24 to the `line wire 1, which short circuit extends around the magnet 16 andth'us` permits denergization of same.

shells 32 so to calla The time interval betweenA im,- pulses is so short that while1armaturef12 is released the armature 15 of the slow release.

magnet 16 does not fallback but permits the pawls 11 and 14 to remain lin en agement.

iter the with the teeth of the element 6.

required numbecof impulses have been sent so that 'arm 7 engages spring 8, then the key 4 .isheld inits closedposition, at which time'ill'ements 7 and 8 are in contact. 'This line circuit remaining closed, permits the 'circuit through elements 7 and 8 to remain closed, thereby short circuiting the magnet 16 and ermittin its armature 15 to fall away an engage its back contact 19. This finally completes the circuit through the lo cal signal 22, which thereupon operates by virtue of the current supplied from the battery 3.l When lthe armature 15 is thus released, while the armature -12 remains at.

tracted, only during the signaling operation, the pawl 14 bends and is not sutliciently strong to withdraw pawls 11 and 14 from the teeth of the element 6 .on account of the. pressure exerted by the pawl 11 against the tooth of the element 6, which it engages. After the signal 22 has been operated a sufficient length of time, key 4 is released and :l thereu on armature 12 is retracted, where-r` upon t e spring action of the pawl 14 which tends t0 move 1t in an upwardlyl direction-,"-

'spouse to impulses -o a greater number than arerequired consideration. The bell 22 thus need not be adjusted closely so'as' to avoid its operating on passingl contacts." -It requires-'the for the particular station under elapse of a certain time interval after the elements 7 and 8 have contacted at the particular station desired,l during which the armature 15 is released to complete the bell i15- circuit. N o adjustment of the bell 22A therefore is necessary to avoid its operating on l passing contacts. The4 great advantages of thus arranging the circuitand the elements to avoid this objectionable feature will Vbe apparent.

The .intention may of course be 'readily applied to many other systems withY like vention may'take without in any way mi tending to limit myself thereby, but

.Harms my' invention, what I `'claim as new and desire to secureby Letters Patent is:
